X.25 Timer Properties

Acknowledgment delay

Defines the maximum amount of time, in .1-second units, before an acknowledgment frame must be sent. The default is 5, and the range is 32000.

Restart request (T20)

Configures the maximum time, in .1-second units, to wait for a restart confirmation or restart indication before issuing another restart request. The default is 1800, and the range is 1 to 32,000.

Call request (T21)

Configures the maximum time, in .1-second units, to wait for a response to a call request--a call connected or clear indication packet--before issuing another call request. The default is 2000, and the range is 0 to 32000.

Reset request (T22)

Configures the maximum time, in .1-second units, to wait for a response to a reset request--a reset confirmation or reset indication packet--before issuing another reset request. The default is 1800, and the range is 0 to 32,000.

Clear request (T23)

Configures the maximum time, in .1-second units, to wait for a response to a clear request--a clear confirmation or clear indication packet--before issuing another clear request. The default is 1800, and the range is 0 to 32,000.

Window status transmit (T24)

Configures the time, in .1-second units, to wait to acknowledge received packets because the peer is experiencing flow control problems. When this timer expires, an outstanding acknowledgment in a receive-not-ready packet is sent. This timer ensures that the unacknowledged packets do not cause a LAN interface reset. The default is 750, and the range is 0 to 32,000.

Window rotation (T25)

Configures the window rotation timer, which is the maximum time in .1-second units to wait to update the receive sequence to reopen the transmission window. (Delaying this reopening is a flow control method.) The default is 1500, and the range is 0 to 32,000.

Interrupt response (T26)

Configures the interrupt response timer, which is the maximum time in .1-second units to wait for a response to an interrupt packet--a DCE interrupt confirmation packet--before issuing another interrupt packet. The default is 1800, and the range is 0 to 32000.
